mechanical do you mean electric coal or any motion.
because catapults could be considered mechanical
It wasn't discovered, but seen by early man. How it was there was answered in myths and mythology by man.
An electric generator is a device used to convert mechanical energy into electrical energy, Which is used to convert mechanical energy into electrical energy. The generator is based on the principle of "electromagnetic induction" discovered in 1831 by Michael Faraday, a British scientist. Faraday discovered that if an electric conductor, like a copper wire, is moved through a magnetic field, electric current will flow (be induced) in the conductor. So the mechanical energy of the moving wire is converted into the electric energy of the current that flows in the wire.
If an object has kinetic energy, then almost BY DEFINITION it has mechanical energy. "Mechanical energy" is the sum of kinetic energy and potential energy.
Most of the devices that we use in society is a kind of mechanical energy. Mechanical energy is the energy of the other. Elevators. Convert electrical energy into mechanical. The car. Converted to mechanical energy is fossil. A bicycle. Muscular body converts energy to mechanical energy.
potiental energy
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
As far as I know, there is no such thing as "mechanical heat energy"; there is mechanical energy, and there is heat energy.
a mechanical energy is a kind of energy
The same year that man discovered fire.
Mechanical energy is the combination of kinetic energy and potential energy.
electrical to mechanical
A generator changes mechanical energy into electrical energy.
